SEAL-LOCK For. FARE-BOXES.

Application filed. August 8, 1914.

To all whom it may concern:

Be it known that I, DOMINA QUINTAL, a subject of the King of Great Britain, residing at No. 3165 St. Dominique street, Montreal, Province of Quebec, Canada, have invented certain new and useful Improvements in Seal-Locks for Fare-Boxes; and I do hereby declare that the following is a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The invention to be hereinafter described relates to fare boxes.

in order to more clearly disclose the construction, operation, and use. of the invention, reference should be had to the accompanying drawings forming part of the present application. 1

Throughout the several figures of the drawings like reference characters designate the same parts. i

In the drawings: Figure 1 is a side view of the box; Fig. 2 is a detail of the key; Fig.

' 3 is a section on line 5-5 of Fig. 1. looking in the direction of the arrows; Fig. 4 is a central, vertical, sectional view through the key hole and lock; and Fig. 5 is a detail view of the key hole.

The main objects of the invention are, to provide a neat, durable, and eflicient fare box which is easily and quickly operated and can not be opened without leaving evidence of the fact, and can be produced at a. relatively low cost.

Referring to the drawings in detail, 1 designates the body of the box, of usual construction, to which is hingedly connected the top 2.

For locking purposes, the top 1 is provided, at the lower edge of its back, with a centrally located bolt l fixedly secured thereto, and provided with a shouldered semicircular head. Bolt 4 cooperates with gripping jaws 5 secured to the inner face of the back of body portion 1. The jaws 5 are of laminated construction, being arranged in superposed pairs, the jaws of each pair being integrally connected to a common base plate 6, by leaf springs 7. The jaws of each pair are each provided with a quadrantal opening, s0 arranged in each pair as to form a semicircular opening adapted to receive the head of bolt 4, with ears 8 adapted to fitover the shoulders thereof, as in Fig. 3.

Specification of Letters Patent.

Patented Nov. 23, 1915. Serial No. 855,794.

When the box top is closed down, the head of bolt 4 forces the jaws apart until it is in the semicircular opening thereof. As soonas it reaches this position, leaf springs 7 act to return the jaws to their original position and snap ears 8 over the shoulders of the head of the bolt, thus securing it in locked position. To unlock the box the key shown in Fig. 2 is provided, which is operative in a specially constructed key hole through the top of handle 11. This key hole is provided with three chambers all connected by the central bore 9, the key openings of which are alternately at right angles to each other. The key, when properly inserted receives the usual key post 10 in its inner end. The key post is secured near the upper end of a leaf spring 11, centrally located between the leaf springs 7 of jaws 5 and secured at its lower end to the base plates 6 of the jaws. The top of spring 11 extends almost to the top opening of the jaws, and the jaws are provided with an elliptical opening around key post 10, of sufficient height and properly situated to receive the bit of the key. On the inner face of spring 11, opposite stud 10, a block 12 is secured. This block is located directly opposite an opening 18 through a partition 14; secured across the box at this point. Opening 13 is covered by a piece of paper 15, or other easily broken substance, bearing the number of the box or other mark of identification.

As will be noted from Figs. 1 and 4, the block 12 is a very short distance from the covering 15, which is not visible from the outside of the box. As shown in Fig. 2, the barrel of the key extends a slight distance beyond the bit. To insert the key suiiiciently to bring the bit between the jaws 5 it is necessary to force the spring 11 in so far that block 12 is forced through the covering 15, thus breaking it. It will thus be seen that it is impossible to open the box without breaking the covering or seal. The portion of the jaws around the opening which receives the bit of the key are, of course, varied to be properly operated thereby. When the key has been inserted so that its bit is entirely within the elliptical opening of the jaws, it is given a quarter rotation. This brings the bit into a horizontal position and forces the jaws outwardly, so as to withdraw ears 8 from the shoulders of the head of bolt parts of the invention, without in any way departing from the field and scope of the same, and it is meant to include all such w thin this applicatlonvwhereinonly a preferred form has been disclosed.

liaving thus fully described my invention, what I claim as new and desired to secure by Letters Patent is: 7 1. In a device of the character described, locking means comprising, superposed pairs of spring mounted jaws provided with semi- -.circular" openings near their upper ends having lateral ears, and elliptical openings below the said semicircular openings, a leaf spring located in back of said jaws and provided with a stud in alinement with the said elliptical opening through the jaws, a seal located in back of the said leaf spring, and means for breaking the seal when the leaf spring is forced inwardly.

2. In a device of the character described, locking means comprising, superposed pairs of spring mounted jaws provided with semicircular openings near their upper ends having lateral ears, and elliptical openings below the said semicircular openings, a leaf spring located in back of said jaws and pro- Vided with a stud in alinement with the said elliptical opening through the jaws, a seal located in back of the said leaf spring, and means carried by the said leaf spring for breaking the seal when the leaf spring is forced inwardly.

3. In combination in a device of the character described; superposed pairs of spring mounted jaws provided with semicircular openings near their upper ends having inwardly eXtending lateral ears, and elliptical openings below the said semicircular openings; a leaf spring located in back of said jaws and provided with a key stud in alinement with the said elliptical opening through the said jaws; a fixed partition mounted in back of said leaf spring and pro vided with an opening; easily breakable closure means secured across the said opening of the partition; and a block carried by the said leaf spring and adapted to engage and break the said closure means when the spring is forced inwardly.

In witness whereof I have hereunto set my hand in the presence of two witnesses.
